If there is enough karma, the result will be ripe. what's the meaning

Good is rewarded with good, and evil with evil. It's not that the time has not come. There are enough karma, and karma will definitely come. For example, when we help others or give alms, we have to do three rounds of empty bodies, that is, there is no giver, no receiver and nothing. The biggest advantage of this way of giving. Wait until one day, when the giver needs help, someone will naturally lend a helping hand. So we must do all the good, not all the evil, because karma is not happy at all.
